Board Revision History

Find out your board revision with the following command:

cat /proc/cpuinfo

You will see your device data including:

Hardware : BCM2708
Revision : 0003

If you see a "1000" at the front of the Revision, e.g. 10000002 then it indicates[1] that your Raspberry Pi has been over-volted, and your board revision is simply the last 4 digits (i.e. 0002 in this example).

ECN0001

ECN0001 is the request to not fit D14 and replace F1 and F2 with 0 ohm.

D14 Removal

D14 can interfere with some CEC devices if the Pi is left plugged in and unpowered. The benefits of having it are minimal so it was removed.[2]

F1 & F2 Replacement/Removal

F1 & F2 can cause problems with some USB devices which draw high current. In particular due to the recovery characteristics of the Poly-fuses, it can take a while to recover their low resistance state afterwards, adding
additional problems for other devices (lower voltage on the USB bus).

Model B Revision 2.0

Based on a new PCB layout that includes previous build fixes from ECN0001 such us removal of the poly-fuses in series with the +5V power for USB devices, and other fixes reported by the community such as the erroneous connection of the LAN9512 VDD18CORE pins to the +1V8 power plane, addition of the 8-pin P5 header (non-populated) for extra GPIO pins, addition to the 2-pin P6 header (non-populated) for a RESET button, and other changes and improvements reported in more detail [3].

Colour Variations

The vast majority of the Raspberry Pis produced have a Green PCB, but Pis produced by Egoman_Technology_Corp (only available in the Far East) have a Red[4] PCB, and RS Components produced a limited edition of anniversary Pis in Blue[5].

Raspberry Pi Model-A Full Production Board

The Foundation produced a small Beta batch before handing manufacturing over to RS and Farnell

The ModelA boards actually use the identical Revision2.0 PCB as ModelB boards, just with a different selection of components fitted (full details available from the schematics). AFAIK no ModelA boards using the Revision1.0 PCBs were ever publicly available (or indeed ever made?).

Raspberry Pi Model-B Full Production Board

The RPi full production board (Model B Rev 2.0)

Announced: April 2012, first orders sent out June 2012.

Manufacturing and Orders will be made through RS and Farnell

This means a much higher volume of units will be produced and made available.
